Is a dell optiplex 745 good for gaming?

So i was looking into getting a new computer, and was just wondering if this was good for gaming, for example, is it laggy, i will mostly be playing minecraft on it and possibly be recording with microsoft encoder 4, all i need to know if it is laggy, and has somewhat ok graphics Thank you!

It will make minecraft laggy but if you stay on the low settings you will be ok, screen recording is just out of the question though, unless you want 5fps (to be simple ALOT of lag). The graphics will be ok with minecraft but I may want to advise you to get a better one, since this one will get outdated soon (might not be able to play minecraft eithout alot of lag) and it will probably run windows xp which recently stopped being supported a couple of weeks ago, which may make you need to upgrade to windows 7 (not 8 because it will just make minecraft and everything else lag).
